Electronic voting machine

ABSTRACT

An electronic voting machine is disclosed which accommodates for selection of one, and only one, candidate from each of two office groups. Electronic logic circuitry is used throughout. The logic features redundant interlocks to assure (1) that overvoting in either office group cannot occur and (2) that a vote cannot be counted unless a selection has been made in both office groups. The interlocks feature redundancy while minimizing the components needed to accommodate for large numbers of candidates in both office groups, and also a combined cancelafter vote reset arrangement which both prevents overvoting and causes reset after vote completion. Another feature of the system is the use of parallel tallying devices each capable of printing out its tally, one such device being the electromechanical counters usually associated with a voting machine and which tally the votes for the individual candidates, and the other such device being an electronic accumulator which likewise counts or tallies the votes for the individual candidates. At the end of a voting day, a print-out of the electromechanical tally and the accumulator tally is made. The accumulator tally print-out is made sequentially much in the fashion of an adding machine, while the print-out of the electromechanical counters is made in one pass of a movable platen. The accumulator has the capability of providing a digital read-out of the voting at all times so that, if desired, the accumulator may be connected, along with a great number of others at different voting sites, to a central computor which may then give an instantaneous tally of the vote for an entire district, state or nation. Both print-outs produce a tally sheet having type which may be be optically scanned to produce a digital output which, from a central location receiving a number of such tally sheets, may forward this digital information to a central computer, as before, at the end of a voting day. Other flexibilities are also presented by the parallel electromechanicalelectronic accumulator system.

At the end of a voting day, a print-out of the electromechanical tally and the accumulator tally is made. The accumulator tally print-out is made sequentially much in the fashion of an adding machine, while the print-out of the electromechanical counters is made in one pass of a movable platen.
